participation of universities, foundations etc.
"As an urgent task for the future, I deliberately call the
African continent, which deserves the attention of a
leading technical university, more than in the past." He
then listed the "great challenges to society": Health and
Nutrition · Environment, Climate and Energy · Natural
Resources · Infrastructure and Mobility · Information
and Communication.” (Translation from German)

anniversary of the TUM: 150 years TUM. Innovation since 1868.

Proposal: Institutes for Development and
Dissemination of Appropriate Technologies, e.g.
African Research and Technology Institutes for
Sustainability (ARTIS)
A famous example of the development and diffusion of appropriate
technologies is the D-Lab at the Massachusetts Institute of Technology (MIT),
founded 15 years ago by Amy Smith (center of picture),
also exemplary through global cooperation.

Traditional charcoal in African households –

For traditional kilns, up to approx. 6 tons of logs and thick branches
are used per household per year.
The reduction of this wood consumption with the help of
Appropriate Technology corresponds
to a saving of approx. 8 tonnes of CO 2
emissions per year.
This corresponds to the emission of a car drive of about 50,000 km,

About space requirements of a pilot garden city
If 2000 family gardens with 500 square meters each are connected
to a garden city with community facilities,
then such a garden community has an area requirement of
approximately one square kilometer
In addition, a 35 times larger economic area (35 sq km)
(for cultivation of staple foods, trade, energy plantations, bio-carbon
sequestration ...)
On an area of the size of Zambia (about 750,000 sq km)
about 1/3 billion people could live (largely self-sufficient)
in pleasant garden communities.

How can we overcome the barriers to spreading of Appropriate Technology?
• No spreading of "poor people technique"
• The criteria of Appropriate Technology (AT) should not become a real obstacle (for example, not just allow local material ...)
• So do not adhere to primitive manufacturing processes and materials
• Use funding sources
• Use the opportunities of television, not just the internet

Exhibitions for sustainable development
Exhibitions on sustainable development can help in the dawn of the necessary changing in our use of the resources of our planet.
and they can provide a forum for global peacekeeping cooperation.
